At low rpm Hc is 125 and allowable is 100 what would cause this. There are no codes and check engine lite is off.
Do you
have the same problem?

There are a few quick fix alternatives;

There is a product called, "Guarantee to Pass", which you can find at your local NAPA, AutoZone, Advance or any chain auto parts store.

The other is to run a can or two of BG44K through your fuel system. It will take some time as each can treats a full tank of gas and you will need to change your oil afterwards. This is because it is so good at removing all the carbon a gunk buildup that it makes your oil dirty. It would be a good idea to replace the spark plugs as well. BG44K is the only fuel injector/ fuel system and combustion chamber cleaner that really works. You will have to go to a dealership or gas station to get it. If you can't find that, you can use a product called, :Sea Foam", which you can find at an auto parts store. This will clean up your fuel system and get you better gas mileage. There is no absolute guarantee that you will pass from any product I can recommend. I used to live in Maryland and if you fail an emission test, you can get an extension and if you spend a certain amount of money and it still does not pass, you can get a waiver. You have to provide receipts as proof to get the waiver. Maybe you can do that where you live.
The, "Guaranteed to Pass" product has worked for 2 people that I know of. So, it is the best quick fix. The BG44K is a good maintenance and will probably get you to pass, along with plug replacement, that it is worth the long term benefits.
The overall problem is a combination of things if you have never used fuel system cleaner, if the car needs a general tune up, etc.
The root cause of the Hydro-Carbons level is a combination of the aforementioned and a new oxygen sensor.

If you have any more questions, I will keep an eye on this post for your reply and get back to you ASAP.
